factorytest.cs

一个工厂模式的源码 采用反射技术 通过设定config文件配置加载类

using System;
using System.Collections.Generic;
using System.Text;
using System.Configuration;
using System.Runtime.Remoting;
namespace Factory_Method
{
    public class FactoryTest
    {
       //增加新的对象时 此代码不变
        public void Test()
        {
            IFactory Ifactory = (IFactory)Activator.CreateInstance(Type.GetType(ConfigurationManager.AppSettings["curcar"]));
            ICar car = Ifactory.GetCarIntance();
            car.Run();
        }
    }
}
